Springboot项目启动成功后执行一段代码的两种方式

方法一:实现ApplicationRunner接口

/**

@Component
public class ApplicationRunnerImpl implements ApplicationRunner {
    @Override
    public void run(ApplicationArguments args) throws Exception {
        System.out.println("通过实现ApplicationRunner接口,在spring boot项目启动后打印参数");
        String[] sourceArgs = args.getSourceArgs();
        for (String arg : sourceArgs) {
            System.out.print(arg + " ");
        }
        System.out.println();
    }
}

方法二:实现CommandLineRunner接口

/**
 * @author lnj
 * createTime 2018-11-07 22:25
 **/
@Component
public class CommandLineRunnerImpl implements CommandLineRunner {
    @Override
    public void run(String... args) throws Exception {
        System.out.println("通过实现CommandLineRunner接口,在spring boot项目启动后打印参数");
        for (String arg : args) {
            System.out.print(arg + " ");
        }
        System.out.println();
    }
}
